Diamonds are forever?

Interesting article thinking forward to the future, having diamond chips etc seems really cool to me.

Wonder what this would do to prices....

I dont get how a totally insulating extended tetrahedral carbon lattice can in any way be a semi conductor though!? Unless they plan to dope the carbon? Or ...? Got me confused.

Prices wont change - they are *making* the diamond themselves in a controlled environment so no impurities, which, at a guess costs just as much as making 99.99999999% pure silicone for electronics wafers.

Screw diamond chips... I want a damn Diamond SHEET case!

I did part of my final year project on semi conductive diamond , so its possible :-)
DeBeers worked out a way of depositing Diamon layer , by a CVD ( Chemical Vapour Deposiiton process ) - this led to small ammounts of gasous doping ( like a conventinal semiconductor works )

after all , pure silicon is a very poo conductor , by conventional methods , its only when you dope it that it gets free electrons in the lattice

wow I can beleve I'm actually remeberin any of my Materials Eng stuff - went to a metal vault after I moved into IT as a job, not Materials!
